Children who follow the routine childhood immunization schedule  (Government of Ontario) will receive all the immunizations needed at the right time to attend school.

Having up-to-date immunizations:

  • helps ensure that children have the best protection possible against certain diseases
  • helps reduce the risk of disease outbreaks in schools and child care settings

Up-to-date immunization records informs Public Health of vaccine coverage rates, which allows us to act quickly should cases of vaccine preventable diseases occur in the school or child care setting. Children with incomplete immunization records may be excluded from school or child care during vaccine preventable disease outbreaks.
